Pragmatism - rationalism are epithets that describe the work that is proposed. Founded in Brussels there ten years, our production workshop consists largely of school projects sustainable architecture clean and simple, against the current of thought smoothed by the gesture free. research in permanent, we focus on repetition, except, development to testing, the duration of the event, common sense sophistication, contrast as a source of astonishment and accuracy as a source of balance. We the belief that the architect must first offer generous space and robust architecture that is made daily right angles and the adequacy of the project budget is essential. The use of serial techniques and materials diverted from industrial architecture (eg externalizing external traffic to maximize the available space and reduce maintenance costs) or by the use of raw materials (raw concrete, wood, polycarbonate ...) can contain a maximum construction budget while characterizing the structure. sustainability is proposed to be taken in a broad sense and includes installation, mobility management, accessibility for all, efficient use of energy and the water, responsible use of materials, maximum flexibility, and anticipation of minimal maintenance. refined this vision can generate the emotion of a practice adopted formally and politically engaged. "Do not make something UNLESS it is Both Necessary and useful; purpose if it is Both Necessary and useful, do not hesitate to make it beautiful!
